WILLIAM A. TURBAYNE, OF

BATTERY COMPANY, A CORPORATION OF NEW YORK.

ELECTRICAL To all whom it may concern:

Be. it known that I, WILLI nu A. TonnM'NE. a citizen of the United States, and.

a resident of Lancaster,`in the county of Erie, State of New York, have invented certain neivand useful Improvements in Electrical Systems of Distribution, of Whicli'the following is a speciiication.

My invention relates to electrical systems cic distribution and more especiallyto the better regulation of boosters in .systems where theyT are employed to govern the action cfa storage apparatus. systems of the above class it hasbeen customary to provide a sole regulating means which embraces agenerator .operating to e-X cite the booster iield.` One of the'great disadvantages of such a regulating means is that it fails to respond quickly enough to certain sudden changes or peaks in the load on the system. 'peaks especially of short duration, are therefore taken by the main generatorl of the system, and notby the storage apparatus or battery.

The objects of my invention areg'enerally to provide a better system of regulation for such systems and princi allyv to provide means whereby these sudden changes or taken by the storage apparatus or battery and the load on the generator'will in' nol case exceed its approximate normal value. 'In the accompli 'hment of these objects .Ifpro- Brlvide a transformer the primaryof Which'is of the 'syste-in.

that the more rapid and lgreater the increase in and effective is the transformer for increasing the booster the battery to discharge into the. main circuit to take the increase in load. 'These and more specific features of my invention'will be more fully described in the detailed description given below With theD accompanying drawing which shows'a diagrammatic viewof a isystemembodying one form of my invention.

In a system of electrical distribution, the combination of amain generator, a circuit connected thereto, a storage device and a booster connected to 'said circuit, means for regulating said booster responsive to "gradua changes in the electrical condition ofthe system, and a transformerin said cir cuit responsiveV to sudden changes in the grees from the points of electrical difference of potential, a magnetic field Will be set up, the uxof which will be parallel to the flux produced by the external field windings of the generator. In'carrying out my inventionI employ these principles and'to that end the booster D is provided with brushes 5,71, contacting with the commutator approximately at the points of zero d1lference of potential. Placed in series in one of the mains,l 2, are the primary coils F of a transformerF. The secondary coils F2 of the brushes b, D, and the circuit c, is com leted through the armaturecoils of the Ooster. Now if a sudden increase of load through the primary cause an electromotive force to be set up 1n the coils F2 and a current will flow through the circuit, c, and the booster armature. This current will produce a magnetic field in the booster 'in such a direction as to cause an increaseof the electromotive, force produced inthe booster, and this increase in electromotive force Will be in such a direc# tion tl at it will cause the battery to discharge'iiitothe mains 2, 2, and supply the eXtra-current due to the increase in the load. esv of transformer lotion it will be understood that the eater and more rapid the sudden n.change 1n load,l the greater will be the electromotive force produced in the' secondary coils F2 and the more quickly and effectively will this electromctive force act upon the booster to produce the required field strength therein.'
